This phrase is incredibly useful for explaining to other, lesser-tech people how they should deal with you as the BOFH (or, as Morgan Freeman's Joe Clark would say, the HNIC).

Example:

LUSER (said with superior you're-so-bluecollar whine): "Oh, Mr. Network Admin, my email doesn't work, and it's because you screwed up my password...can you take time to fix that right now since my email is mission-critical?"
